Valve has announced a new game for the Portal series, but it’s not exactly Portal 3. This next game will be a crossover title between the Portal series and Bridge Constructor. The game, Bridge Constructor Portal, is a Bridge Constructor-puzzle game with new mechanics from the Portal series. Like most Bridge Constructor titles, you’ll need to get trucks from one side of the screen to a goal on the opposite side. In this title, however, you’ll need to use portals to warp your vehicle properly to the exit. A PC and mobile version will release on December 20th. Afterwards, you can expect a console release in the months to come. The trailer showcases logos indicating that it’ll arrive for Xbox One, PS4, and Switch.
